Ignition Coil & Iridium Spark Plugs for BMW 328i E90 (2007-2013) 3.0L I6

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2007-2013 BMW 3 Series

Restores proper combustion and eliminates misfire codes: This complete ignition service kit replaces degraded factory coils and fouled plugs to ensure optimal spark delivery and consistent idle stability for the N52/N51 naturally aspirated powerplants.

The Stock 3 Series Ignition Shortcomings

The OEM ignition system on the E90 chassis, specifically paired with the N52 3.0L engine, is highly susceptible to thermal degradation. Situated directly above the exhaust manifold and nestled under a tightly packaged acoustic cover, the factory ignition coils endure severe heat soak cycles. The internal windings increase in resistance, and the epoxy potting compound begins to crack. This thermal breakdown leads to weak spark propagation, hesitation under load, erratic idle characteristics, and the inevitable triggering of P0300 to P0306 misfire diagnostic trouble codes (DTCs). Simultaneously, standard spark plug electrodes wear down, widening the gap and further straining the aging coil packs.

The Engineering Solution

This comprehensive ignition refresh kit addresses these inherent electrical failures by utilizing upgraded materials for both the coils and the plugs. The newly designed ignition coils feature high-grade silicone boots that resist cracking and dielectric breakdown caused by extreme engine bay temperatures. Internally, enhanced copper windings with improved insulation ratios deliver a more potent voltage output to the spark plugs, overcoming the increased resistance of heat-soaked environments. Paired with the coils are precision-gapped Iridium spark plugs. The ultra-fine iridium center electrode significantly reduces the voltage required to jump the spark gap, decreasing the operational load on the ignition coils while ensuring complete fuel vaporization. This results in crisper throttle response, restored fuel economy, and reliable starting in cold climates.
